SURFACE CONDENSER. v

denser to be cleaned while the other section is in operation.

An object of the present invention is to provide an improvedair cooler or condenser of a type whereby the air will be effectively cooled when the condenser is operating at full surface or when only one section thereof is in operation.

The invention comprises, a condenser iii which the air offtake from the air cooler is f baiiied so that air crosses the tubes on both sides of the water division diaphragm whereby the air crosses the tubes through which the cold water is circulated whether the water is circulated through both sections or only through one section of the condenser, and in which short circuiting of steam to the air pump is prevented under all operating conditions of the condenser. Y

With these objects in View, the invention consists in various features of construction and combination of parts, which will be first described in connection with the accompanying drawings, showing a surface condenser of the preferred form embodying the invention, and the features forming the invention will be specifically pointed out in the claims.

In the drawings- Figure 1 is a cross section through a condenser constructed -in accordance with the present invention.

Figure 2 is anV end elevation of a condenser constructed in accordance with the present invention showing the dividing partition and other features which permit'divided water circulation through the condenser.

Fig. 3 is a sectional view of the condenser p taken on the line S-B'of Fig. 1.

Referring more particularly to the drawings, in Figure 2 is illustrated, in end view.y a asurface condenser in which the interior of the water box 1 is divided vertically by the partition 2 forming a right handsection 3 and a left hand section 4t. The cold circulating water has independent circulation through the sections of the condenser, it entering the section 3 through the inlet pipe 5 and passing from the ysection 3 through the outlet 6, while a separatev and distinct inlet 7 and outlet 8 for the circulating Water are provided in connection with the section 4. rIhis construction permits oneshalf or one section of the condenser to operate while the other half or section is .shut down, preferably for purpose of cleaning the tubes or for any` other repairs which might be necessary and at such times access to the tubes in theshut down section of the condenser is had through man-holes which are lnormally closed by the cover plates 20. A

In the construction of condensers of this type having divided water circulation, it is desirable to properly cool the air to reducel its volume so as to enable it to be handled by a relatively small pump, to circulate the air acrosscooled tubes,and as shown in Figure 1 of the drawings the air cooling part of the condenser is at its lowest portion, and the air passes transversely across the tubes 9.

To prevent air from being drawn through the air suction pipe 10 without its being properly cooled, or passing over tubes through which the water is circulated, at times when one section of the condenser is shut down, a

plurality of baffles 11 are provided whichV eX- a tend across and 'on each side of the central partition 12 in the condenser 1. The bafHes 11 are arranged so that the air passing to the n air suction -10 will be directed in a sinuous path across the tubes 9 in the air cooler section of the condenser causing the airto pass across the tubes 9 iii both sections 3 and 4 of the condenser tol insure its passage over tubes through which the cold water is circulating.

It will be understood that theinvention is not to belimited to the specific construction `or arrangement of partsshown but that these may be modified widely within the invention defined by the claims. f

What is claimed isi v l 1, In a steam condenser having divided water circulation and an air outlet, means for directing the air inasinuous path to the air outlet whereby the air will be cooled when the condenser is operating as a whole or only in part. 2. In a steam condenser having an air outlet and divided water circulation whereby the condenser may operate in eitherone or in both of the sections formed by the division of water circulation, a series of baiiies arrangedto direct air passing to said outlet through por-` tions of both of said sections.

3. Ina steam condenserv having an air outlet and divided Water circi'ilation whereby the condenser may operate in either one or in both of the sections formed by the division of water circulation, a series of baiiles ar-H ranged to direct air passing` to said outlet in a sinuous path through portions of both of said sections.

4. In a steam condenser having,` an air outlet and divided Water circulation whereby the condenser may operatein either one or both yof the sections formed by the division of wa-v tercireulation, ,a plurality lof baiiies arranged staggeredly in the condenser and projecting from one section into the other section formed by the division of Water circulation whereby air passing to said air outlet will'be directed in a sinuous path through portions of both of said sections. Y

In testimony whereof I affix my signature.
